The exhaust fan is a type of air conditioning device that is driven by a motor to drive the airflow to drive airflow to exchange indoor and outdoor air. Also known as the ventilation fan. The purpose of the exhaust is to remove the dirty air inside the room and adjust the temperature, humidity and sensation. Exhaust fans are widely used in homes and public places.
The greenhouse exhaust fan is divided into a partition type, a duct exhaust type, a duct inlet type, and a full duct type according to the air inlet and outlet. According to the form of wind flow, it is divided into centrifugal type, axial flow type and cross flow type.
The ventilation mode of the greenhouse circulation fans is three types: Discharge type, suction type, and combined type. The discharge type enters the air from the natural air inlet, and discharges the dirty air through the exhaust fan; the suction type sucks the fresh air through the ventilation fan, and discharges the dirty air from the natural exhaust port; and the suction and exhaust are both performed by the ventilation fan.
1. Automated molding process, high precision 2, extra thick galvanized layer, strong corrosion resistance 3. High-strength alloy casting wheel, light weight, high strength, good toughness 4. New twisted stamping fan blade, leaf the angle is reasonable, the air volume is large, the noise is low. 5. The blinds are automatically opened and closed to achieve the effects of windproof, dustproof, rainproof and beautiful. 6. The rear safety net is easy to disassemble and repair.
